Children and parents waiting for a screening of Frozen to begin at a cinema in Florida last week got a shock when sexually explicit images appeared up on the big screen instead.

The audience was waiting to see the animated feature, the Guardian reports, which was delayed due to a technical error. But as they were waiting, the screen suddenly filled with footage from another film, one featuring graphic sex. One audience member recognized the footage as the trailer for Nymphomaniac, an upcoming art house film from Danish director Lars Von Trier. Parents reportedly wasted no time in high-tailing it to the exits with their children.

Nymphomaniac stars Charlotte Gainsbourg, Uma Thurman, Stellan Skarsgård, Christian Slater and Shia LaBeouf and once released in the U.S., it’s almost certain to receive an NC-17 rating. Even the film’s trailer is extremely graphic, depicting multiple sex acts. Frozen on the other hand, is the latest PG-rated Disney princess film, which has made a killing at the box-office. Honestly, it’s hard to imagine two movies that are any more different.
